After powering up the DSM-312 an Online Upgrade window shows up telling a new firmware found Press OK to Continue. (v1.01.23NA). I press OK and it started the process warning to not disconnect power, then it stopped. After a reasonable time passed I had to remove power. So I attempted it again and again, until for no apparent reason it booted into the system menu and I had to re-configure the network. At this time I went into the system menu and asked for an Online Update and it worked....!!!
